|
Containment box has been replaced onto TM2, interior of containment box vacuumed, and Ta#54 installed with new fasteners (high current torqued to 130
in lbs). |

Thursday, September 28, 2017, 10:50, David Wang, Conditioning Station, Standard Operation, TM2, , Helium pressure test on TM2 window and HS water lines at TCS.
|
I did helium pressure test on TM2 containment box window and HS line at TCS. @ 70psi helium for 3 minutes, HS:2.2XE-7 atm.cc/sec., Window:1.2XE-7
atm.cc/sec. There is no change on HS. But LR on window is bigger than before that was in E -9atm.cc/sec range. |

Thursday, September 28, 2017, 15:34, Anders Mjos, Conditioning Station, Development, TM2, , Changes to MP3 startup
|
Due to problems with the regulating valve WPV1, the VFD (Variable Frequency Drive) for the pump has been programmed to do a slow (2 min) ramp up.
WPV1 has been bypassed and left fully opened. Work was done by Dave Morris |

Thursday, November 09, 2017, 09:34, David Wang, Conditioning Station, Standard Operation, TM2, Ta#55, Leak check on TM2 HS line at SHC and TCS.
|
The TM2 HS line was leak checked at SHC yesterday . 0.9xE-9 atm.cc/sec.Helium sprayed by Chad, NO leak. It was helium pressurized at TCS this morning.
Leak rat:2.5 XE-7 atm.c/sec. The result is same as last time check. No concern. |

Thursday, November 09, 2017, 09:35, David Wang, Conditioning Station, Standard Operation, TM2, Ta#55, TM2 has been connected at TCS
|
| TCS vacuum system and water system have been started as well. Everything looks fine. |

|
Thursday, November 09, 2017, 10:40: BIAS / EL to 30 / 15 kV. 400 uA on BIAS
Bias was stable for 1 hour. Handed over to RIB ops for heater conditioning. |

Monday, November 13, 2017, 13:39, Travis Cave, South Hot-Cell, Standard Operation, TM2, Ta#54 and #55, Electrical Check
|
The results of the various electrical check done on the target module on November 7th and 8th of 2017. Checks were done with the old Ta#54 target
without a target and finally with the new Ta#55 target. See the attached PDF for results. |
|
Tuesday, November 14, 2017, 10:01, Travis Cave, ITW, Standard Operation, TM2, Ta#55, Module move
|
TM#2 with Ta#55 has been moved from the conditioning station to the west target station. The field was measured on the access panel to the service
chase and the field was found to be 430uSv/hr at one meter from the module. |
|
Tuesday, November 14, 2017, 14:34, David Wang, ITW, Standard Operation, TM2, Ta#55, TM2 has been connected in ITW.
|
| TM2 has been connected in ITW. All turbo-pumps are started. Everything works fine. |
|
Wednesday, December 13, 2017, 15:32, Anders Mjos, Assembly/Bench Test, Maintenance, TM2, , Source Tray inspection
|
The Source tray was inspected in the RH shop today by Anders, Friedhelm and Jens. The routing of the lines are satisfactory, however a design proposal
to remove the ground electrode line will be made. This design will have to ensure a proper connection from the electrode to ground (using the window cooling
lines). All other lines are OK at this point. Some fine adjustments are expected after brazing and soldering to maintain high voltage separation. Photos |

Friday, December 22, 2017, 11:09, Anders Mjos, ITW, Standard Operation, TM2, , Shut down High Active Cooling water
|
Stopped MP1 today in preparation for the power outage over the holidays. both P-25 and P-26 breakers have been switched off to prevent inadvertent start
of system |
|
Tuesday, January 16, 2018, 10:36, Anders Mjos, Spent Target Vault, Standard Operation, TM2, , Old TM2 Source Tray moved to Cyclotron basement
|
The old TM2 Source Tray from 2009 has been moved to Cyclotron basement this morning. Source tray was stored in location 9. The box was moved from the
vault to the ante-room yesterday. No contamination was found on the box. |
